Abstract

The invention relates to a headlamp reflector for an automobile vehicle manufactured by injection molding according to the coinjection process using poly(alkylene terephthalate) having a viscosity number (DIN 16,779) of between 60 and 180 cm3/g. It is characterized by the fact that the core contains some 15 to 75% by weight of hematite, at least 75% of the hematite having a particle size less than 70 mu m. Good mechanical strength and good behavior in respect of temperature.
